Custom orders are managed through ourDiscord server. I will discuss the details of your project with you there.
In order for me to get started on your design you'll need tosend me a DM with your order number. I'm AFS - Aaron
Custom bodies don't include changes to the primary case design. They are limited to minor modifications such as changes to the option button and Neutrik holes or other IO holes cut or removed. The overall shape must remain the same. Changes in width (not depth or height) are available though.
Width changes will require a custom button panel as well.
